A) 15B) 225C) 1D) none of the above

Yes the answer will be 225/15*15. As / and * has the same precedednce and associativity is from left to right so it will give 225(225/15*15 => 15*15 => 225).

In algebra * has higher precedence than /, but in C they have the same precedence, and are left-associative, meaning the operations are performed left to right.So 225 / 15 * 15 gives (225/15)*15 or 22...

When a = 0.7internally compiler treats 0.7 as double. Now a is a float and float is always small then double so the if condition is true and answer will beYES

Where is the function declared as static stored in memory?
The usage of static with a function or variable restricts their scope.Is this behaviour memory related?
jbode
- Jun 5th, 2019
The static keyword does not affect where or how a function is stored in memory. It only affects whether the function *name* is visible to code outside of the current translation unit (source file).

You have to specify where you are going to place it. You can do this in the linker file(.lsl or .ld file). If you place it in the .text section, it goes into the Flash, else by default a static function is placed in the RAM(.data).

Get the address by using the unary "&" (address-of) operator. You can display it with printf() by using the "%p" conversion specifier (youll need to cast the argument to "void *"). See below:{geshib...
Difference between reference and pointer?
What is difference between reference and pointer or pass by reference and pass by pointer?
kbjarnason
- Jul 1st, 2010
Since this is posted in a C section, the main difference is that in C, pointers exist and references don't. That's C++.

Is there any advantage of using a reference variable as opposed to using a pointer. I mean pass by reference ( by using pointers ) was implemented in C. Why is this new technique of pass by reference (using reference variable ) invented for C++

There is no requirement to use fflush in multiple scanf calls. fflush operates exclusively on output streams, thus has no relation to scanf, which is an input function.That said, if one is using...
